Melanin (/ ˈmɛlənɪn / ⓘ; from Ancient Greek μέλας (mélas) 'black, dark') is a family of biomolecules organized as oligomers or polymers, which among other functions provide the pigments of many organisms. [1] . Melanin pigments are produced in a specialized group of cells known as melanocytes.

Melanin is a substance in your body that produces hair, eye and skin pigmentation. The more melanin you produce, the darker your eyes, hair and skin will be. The amount of melanin in your body depends on a few different factors, including genetics and how much sun exposure your ancestral population had.

2023年5月1日 · Melanin is a term used to describe a large group of related molecules responsible for many biological functions, including pigmentation of skin and hair and photoprotection of skin and eye. [1] [2] [3] In humans, melanin exists as three forms: eumelanin (which is subdivided further into black and brown forms), pheomelanin, and neuromelanin.

Melanin is a dark biological pigment (biochrome) occurring in the skin, hair, feathers, scales, eyes, and some internal membranes of humans and other animals. It is formed as an end product during metabolism of the amino acid tyrosine.
